Well, it could also house annotations...
It is true that some devices add metadata to the objects they store. I know this from HDS and IBM COS (name index), I do not know anything about Atmos.
But even if it were, it would be completely internal to Atmos and not visibly used by CPE. If one would depend on such device specifics it would be hard to support this plethora of storage devices.
What is the background of your question?
